DescriptionDiamond Systems DMM-32-AT 16-Bit Analog I/O PC/104 Module with Autocalibration.
OverviewDMM-32DX-AT is a PC/104-format data acquisition board with a complete set of analog and digital I/O features. It offers 32 analog inputs with 16-bit resolution and programmable input range; 250,000 samples per second maximum sampling rate with FIFO operation; 4 analog outputs with 16-bit (or 12-bit) resolution; user-adjustable analog output ranges; 31 lines of digital I/O; one 32-bit counter/timer for A/D conversion and interrupt timing; and one 16-bit counter/timer for general purpose use.
Key FeaturesThe DMM-32DX-AT is designed to be a fully backward-compatible upgrade for the DMM-32-AT board. In addition to all DMM-32-AT features, the DMM-32DX-AT includes the following upgrades: 1024-sample FIFO for A/D samples versus. 512 samples on DMM-32-AT 1024-sample data buffer for D/A waveform generation reprogrammable Software FPGA and dsPIC microcontroller for future feature enhancements Patented auto-autocalibration feature that provides fully autonomous calibration in hardware
Analog Outputs4 analog output channels with 16-bit standard, 12-bit optional resolution, 5mA max output current Multiple fixed full-scale output ranges, including unipolar and bipolar ranges Programmable full-scale range Patented hardware-implemented auto-autocalibration 1024-sample FIFO for D/A wave form generation 250 KHz maximum update rate Simultaneous update for all 4 channels capability
Digital I/O24 bi-directional lines using integrated 8255-type circuit Buffered I/O for enhanced current drive Handshaking controls enable external latching of data as well as interrupt operation User-configurable pull-up/pull-down resistors 7 additional I/O lines are fixed direction with programmable functions
Counter/Timers and A/D Triggering1 32-bit counter/timer for A/D pacer clock and interrupt operation timing 1 16-bit general purpose counter/timer Programmable input sources for each counter/timer External A/D triggering and gating inputs Multiple-board synchronization capability using A/D convert pulse out and external trigger in Interrupts may be generated by counter/timer
MiscellaneousExtended temperature –40oC to +85oC operation No trim pots or user adjustments are required for calibration. Auto autocalibration will automatically adjust the A/D without user input. The calibration time for all modes is approximately 2 seconds. Auto autocalibration of one A/D mode using the onboard dsPIC requires approximately 0.5 seconds.
